Ordered semigroup

WebA partially ordered semigroup (or a po-semigroup for short) is a structure A =(A,≤,⋅)where ≤is a partial order and ⋅is a binary operation that is associative and order-preserving in both variables. If x⋅y≤xand y⋅x≤ xfor all x,y∈A, then A is called two-sided (or negative [5]).

Left and right identities are both called one-sided identities. A semigroup may have one or more left identities but no right identity, and vice versa. A two-sided identity (or just identity) is an element that is both a left and right identity. Semigroups with a two-sided identity are called monoids. A semigroup may have at most one tw…

WebIf S is a partially ordered semigroup such that all left and all right translations are γ-continuous (i.e., Y∈γS implies {x∈S:y·x∈Y}∈γS and {x∈S:x·y∈Y}∈γS for all y∈S), then S is called a γ-semigroup. WebAn ordered semigroup is a semigroup S equipped with a stable order relation on S. Ordered monoids are de ned analogously. The notation (S; ) will sometimes be used to emphasize the role of the order relation, but most of the time the order will be implicit and the notation Swill be used for semigroups as well as for ordered semigroups.
